Barely wider than a strand of human DNA, magnetic nanoparticles - such as those made from iron and platinum atoms - are promising materials for next-generation recording and storage devices like hard drives. Building these devices from nanoparticles should increase storage capacity and density, but understanding how magnetism works at the level of individual atoms is critical to getting the best performance.
However, magnetism at the atomic scale is extremely difficult to observe experimentally, e ... read more

Lockheed trims costs for F-35, most expensive plane ever
Lockheed Martin and the Pentagon on Friday said the next batch of F-35 stealth fighters, the most expensive planes in history, will be produced at a reduced cost.
They announced $728 million in savings after President Donald Trump publically upbraided Lockheed over "out of control" costs, although most of the savings were already planned ahead of his involvement, during a months-long contrac ... more

China looks to Mars, Jupiter exploration
China's plans for deep-space exploration included two Mars missions and one Jupiter probe.
China plans its first Mars probe by 2020, said Wu Yanhua, vice director of the China National Space Administration.
A second Mars probe will bring back samples and conduct research on the planet's structure, composition and environment, Wu said.
Also on the agenda are an asteroid explorat ... more

Japan taps Elbit subsidiary for cybersecurity training help Israel's Cyberbit Ltd. is helping launch a cybersecurity training and simulator facility in Japan under a contract from Ni Cybersecurity Inc.
Ni Cybersecurity, a Japanese firm, will set up a training facility in Toranomon, Tokyo, to accelerate the certification of new cybersecurity experts and helping organizations improve the skills of their existing staff, focusing on government and f ... more

Complete Lunar-cy: The Earth Has Sprayed the Moon With Oxygen for Billennia
The Moon may be peppered with oxygen transmitted by life on Earth, according to a scientific study, opening up the possibility that the Earth's atmosphere of billions of years ago may be preserved on the present-day lunar surface.
It has long been speculated that the Moon has been intermittently sprayed with the Earth's oxygen, with some researchers suggesting the nitrogen and noble gases ... more

500 years of robots go on show in London Why do humans build machines that resemble them - and what does that say about us? A London exhibition opening on Tuesday is surveying 500 years of simple to sophisticated robots to find out.
Take a lip-syncing monk from the 16th century or a cartoon-like humanoid avatar that helps children with autism today. They and 100 other robots on display at the Science Museum chart an evolution of m ... more

DARPA demonstrates SideArm UAS capture system The U.S. Defense Advanced Research Projects Agency recently demonstrated the capabilities of its SideArm, a device built to catch unmanned aircraft in flight.
In a test conducted by Aurora Flight Sciences in December 2016, the SideArm was used to catch a Lockheed Martin Fury unmanned aircraft system weighing 400 pounds. While DARPA aimed to create a device capable of catching 900-pound ... more

First ever blueprint unveiled to construct a large scale quantum computer
An international team, led by a scientist from the University of Sussex, have unveiled the first practical blueprint for how to build a quantum computer, the most powerful computer on Earth.
This huge leap forward towards creating a universal quantum computer is published in the influential journal Science Advances (1). It has long been known that such a computer would revolutionise indust ... more

New beam pattern yields more precise radar, ultrasound imaging University of Rochester researchers have developed a novel beam pattern that promises to lend unprecedented sharpness to ultrasound and radar images.
The beam's mathematical pattern yields wavelengths that momentarily collapse in on themselves, briefly forming a precise and powerful beam of sound or light waves.
"All the energy fits together in time and space so it comes together ... more

Exile, jail, abduction: the hazardous lives of China's rich The mysterious case of a billionaire who went missing from Hong Kong last week, reportedly abducted by mainland security agents, has underscored the precarious lives of China's ultra rich.
Local media say financier Xiao Jianhua was last seen at his apartment in Hong Kong's Four Seasons hotel and is under investigation in connection with China's 2015 stocks crash.
There is no shortage of ... more

Research pushes concept of entropy out of kilter
Entropy, the measure of disorder in a physical system, is something that physicists understand well when systems are at equilibrium, meaning there's no external force throwing things out of kilter. But new research by Brown University physicists takes the idea of entropy out of its equilibrium comfort zone. The research, published in Physical Review Letters, describes an experiment in which the ... more

Cosmologists a step closer to understanding quantum gravity
Cosmologists trying to understand how to unite the two pillars of modern science - quantum physics and gravity - have found a new way to make robust predictions about the effect of quantum fluctuations on primordial density waves, ripples in the fabric of space and time.
Researchers from the University of Portsmouth have revealed quantum imprints left on cosmological structures in the very ... more

Powerful change: A profile of today's solar consumer
People with higher incomes and better education no longer dominate demand for the domestic solar market in Queensland with a new QUT study revealing the highest uptake in solar PV systems comes from families on medium to lower incomes.
Over the past decade the profile of Queenslanders acquiring solar PV has changed significantly based on a study by QUT Dr Jeff Sommerfeld investigating the ... more
